Gearing

Lower gears help on climbs. Higher gears suit higher speeds.

RPM

RPM = pedal turns per minute.

All published sizes46/30T · 12–32T
Lowest0.94:1 Highest3.83:1 Total range409%
Estimated speed At 90 RPM Lowest gear6.9 mph Highest gear28.3 mph

Rear tire: 650B×2.3″.

How it works

Ratio = front teeth ÷ rear teeth. Hub gears also include the hub’s internal ratio. A 400% range means the highest ratio is four times the lowest.

Speeds are estimates from tire size and pedal cadence. Actual speeds vary.
